SHA1Managed UWP (C#)

I writing app for UWP

I have code

 private string Hash(string input)
 {
     using (SHA1Managed sha1 = new SHA1Managed())
     {
         var hash = sha1.ComputeHash(Encoding.UTF8.GetBytes(input));
         var sb = new StringBuilder(hash.Length * 2);

         foreach (byte b in hash)
         {
             // can be "x2" if you want lowercase
             sb.Append(b.ToString("X2"));
         }

         return sb.ToString();
     }
}

But it not works and show this error

Severity Code Description Project File Line Suppression State Error CS0246 The type or namespace name 'SHA1Managed' could not be found (are you missing a using directive or an assembly reference?) Milano C:\Users\nemes\Documents\GitHub\Milano_pizza\Milano\WoocommerceApiClient.cs 25 Active

How I can fix this?

SHA1Managed is only available for Android and iOs, for Windows UWP use:

If you want as a result a byte array:

    public byte[] getSHA1MessageDigest(string originalKey)
    {
        IBuffer buffer = CryptographicBuffer.ConvertStringToBinary(originalKey, BinaryStringEncoding.Utf8);
        HashAlgorithmProvider hashAlgorithm = HashAlgorithmProvider.OpenAlgorithm(HashAlgorithmNames.Sha1);
        IBuffer sha1 = hashAlgorithm.HashData(buffer);
        byte[] newByteArray;
        CryptographicBuffer.CopyToByteArray(sha1, out newByteArray);
        return newByteArray;
    }

If you want as a result a string:

    public string getSHA1MessageDigest(string originalKey)
    {
        IBuffer buffer = CryptographicBuffer.ConvertStringToBinary(originalKey, BinaryStringEncoding.Utf8);
        HashAlgorithmProvider hashAlgorithm = HashAlgorithmProvider.OpenAlgorithm(HashAlgorithmNames.Sha1);
        IBuffer sha1 = hashAlgorithm.HashData(buffer);
        byte[] newByteArray;
        CryptographicBuffer.CopyToByteArray(sha1, out newByteArray);
        var sb = new StringBuilder(newByteArray.Length * 2);
        foreach (byte b in newByteArray)
        {
            sb.Append(b.ToString("x2"));
        }
        return sb.ToString();
    }

For UWP use HashAlgorithmProvider

    public string Hash(string input)
    {
        IBuffer buffer = CryptographicBuffer.ConvertStringToBinary(input, BinaryStringEncoding.Utf8);
        HashAlgorithmProvider hashAlgorithm = HashAlgorithmProvider.OpenAlgorithm(HashAlgorithmNames.Sha1);
        var hashByte = hashAlgorithm.HashData(buffer).ToArray();
        var sb = new StringBuilder(hashByte.Length * 2);
        foreach (byte b in hashByte)
        {
            sb.Append(b.ToString("x2"));
        }
        return sb.ToString();
    }

Remember to add

using Windows.Security.Cryptography;
using Windows.Security.Cryptography.Core;
